Quizplus · Accepted Answer

Label G indicates a bundle of muscle fibers, which is the definition of a muscle fascicle. Triads are structures formed by the sarcoplasmic reticulum and T-tubules. Myofibrils are long, cylindrical structures within muscle fibers composed of sarcomeres. Sarcomeres are the basic functional units of skeletal muscle and are composed of myofilaments.
